What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Port Republic, NJ assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Port Republic, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

What Is A Passing Blower Door Test Score?

In Port Republic, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes.

Preparing for a Blower Door Test in Port Republic, NJ

Preparation for blower door test in Port Republic, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Port Republic, NJ.
